1999 4Runner Limited rear end clank

Have a horrible clanking or chattering coming from rear end of vehicle. Started out just hitting bumps now it's continuous. Also when making sharp right turns onto streets there's a huge vibration and skipping. Reminds me of driving a pedal car when a kid and power sliding. Any ideas? I appreciate any and all input.

 

Did you check the rear upper arms? Sounds like one is broken. Or even a rear lower trailing arm. Check the panhard bar as well
